IMPROVEMENT IN MANUFACTURING BOXES.

Specification forming part of LettersrPa-tent No. 40,507, dated November3, 1863.

To all whom it may concern:

Beit known that I, JOHN Srnnnv, of the city, county, and State of NewYork, have invented a new and useful Improvement in the Manufacture ofBoxes, and I do hereby declare that the following is a full, clear, andexact description'of thet same, reference being had to the accompanyingdrawings, forming a part of this specification, in which- Figure lrepresents a perspective view of a box constructed according to myinvention. Fig. 2 is a similar view of someof its parts during theprocess of the construction. Fig. 3 is a transverse vertical section ofthe same with the cover. Fig. 4 is a modification of the same.

Similar letters of reference in the three views indicate correspondingparts.

The object of this invention is to produce a grain-bound box bycombining several thin layers of wood in such a manner that on everypart of the box the grain of one layer runs in a different direction tothat of the adjacent layer or layers.

The nature of my invention and its advantages will be readily understoodfrom the followingdescription.

A represents a box, which may be square or of any other desired shape orform. When the box is square, its several parts are combined in thefollowing manner: I take two thin pieces of wood, a b, Fig. 2, turn theends a b up to correspond to the desired height of the box, and placethe part a over the part b, as shown in Fig. 2. The grain of the bottomb runs crosswise at right angles to that of the bottom a, and the grainsof the sides a b run in a vertical direction. The sides are nowstrengthened by a band, c, placed inside or outside, or two such bandsmay be used, one inside and the other out. This band is made of onepiece of wood cut out to correspond to the inner or outer circumferenceof the box and to its height, and it is secured to it by glue or othersuitable cement. The grain of band c runs at right angles to the grainofthe sides a b', and by these means a splitting of said sides isprevented. The bottom may be further strengthened by an additionallayer,

d, glued ,to the under surface of the bottom a.

When the box is polygonal or round, itsconstructionis slightly varied,according to the number of sides. All the sides may be made out of onepiece of wood, wt, having its ends a turned in toward a common center,and the bottom is completed by securing to said ends one or two layersof wood, and the sides are strengthened by one or two bands glued totheir inner or outer circumference, or to both, as previously described.A round box constructed according to this principle is represented inFig. 4. The bottom is composed of a series of gores, abt, which areproduced by cutting out the bottom edge of the side piece, c After thesegores have been turned in, so that their points meet in a common center,they are fastened by one layer of wood, which may be applied inside o routside; or two such layers may be used, one inside and the otheroutside, and these layers are so placed that their grains run indifferent directions. The round side wall of the box is strengthened bya band, which may be fastened inside or outside, or two such bands maybe applied, one inside and one outside, as previously described.

What I claim as new, and desire to secure by Letters Patent, is-

1. A grain bound box made of bottom pieces, a a', b b/, and bands c,which are so arranged in relation to each other that the grain of onelayer crosses the grain of the adjacent layer, substantially as specied.

2. Making the bottom and the sides of a wooden box either partially orwholly out of one and the same piece of material by turning the edges upor in, as set forth.
